The invention discloses a material grabbing machine counterweight adjusting system, and relates to the technical field of material grabbing machines, the material grabbing machine counterweight adjusting system comprises a rotary table of a material grabbing machine and a movable arm at the front end of the rotary table, a hinged counterweight mechanism is arranged on the back of the rotary table, the front end of the counterweight mechanism is connected with a traction rope, and the other end of the traction rope is connected with the movable arm; the movable arm turns over to drive the balance weight mechanism to turn over around a hinge point through the traction rope, and a limiting mechanism is arranged on the balance weight mechanism to limit the maximum turning angle of the balance weight mechanism. The balance weight mechanism can be moved backwards through the hinged support, and the torque of the balance weight mechanism to the rotation center is increased. Therefore, the weight of the counterweight mechanism can be reduced on the premise of meeting the material grabbing weight, and the weight of the whole machine is reduced; the adjusting mechanism is arranged to adjust the tension provided by the counterweight, so that the whole machine can be applied to different working conditions in actual use, various adjusting modes can be carried out according to the actual working conditions, meanwhile, the service life of the movable arm ejector rod can be guaranteed, and the power of the whole hydraulic system can be reduced.
本发明公开了一种抓料机配重调节系统,涉及抓料机技术领域,包括抓料机的转台和转台前端的动臂,所述转台背部设有铰接的配重机构,所述配重机构前端连接牵引绳,所述牵引绳另一端与所述动臂相连,所述动臂翻转通过所述牵引绳带动配重机构围绕铰点翻转,所述配重机构上设有限位机构限定配重机构的最大翻转角度。通过铰接支架可以将配重机构后移,配重机构对回转中心的力矩加大。因此在满足抓料重量的前提下,能够减少配重机构的重量,从而减小整机重量;设置调整机构来调整配重所提供的拉力,使得整机在实际使用中能够应用于不同的工况当中,能够根据实际工况进行多种调节方式,同时能够保障动臂顶杆的使用寿命,降低整个液压系统的功率。
